Specification of Letters Patent.

Patented Oct. 9, 1906.

Application filed March 22,1905. Serial No. 251,420.

To all whom it may concern:

Be it known that 1, WILLIAM F. MoRsE, a citizen of the United States, and a resident of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Machines for Making Building-Blocks, of which the following is a specification.

This invention relates to apparatus for making building-blocks, tiles, and other plastic articles, and has for its object a machine that is cheap and portable and one from which the articles can be easily removed when formed and that can be used with molds of different sizes.

Referring to the drawings, Figure 1 is a side view of the machine. Fig. 2 shows in perspective the mold, and Fig. 3 is a section on the irregular line 3 3 of Fig. 1.

The machine comprises three separable partsviz. the bed, the tilting frame, and the mold.

The bed 1 is a rectangular frame of suitable size, preferably an iron casting, with a rack 2 along the inside of each side rail.

The tilting frame is designed to hold the mold, and in order that the mold may standin either one of two positions that are at right angles to each other the frame is made to rock upon the bed. The frame is the width of the bed. Each side piece comprises the arms 3 and 4, that are at right angles to each other and are connected by the segmental gear 5, which meshes with the rack 2 on the same side of the machine. The side pieces of the frame are parallel with each other, and their corresponding arms 3 and 4 are respectively connected at their ends by the rods 6 and 7.

The mold is shown upon its side in the drawings, which is its position when the block has been formed and is to be removed from it. It comprises the side piece 8, the ends 9 9, that are respectively hinged to the edges of the side piece 8, as at 10 10, the bottom 11, that is hinged to the side 8, as at 12 12, and the other side 13, that is hinged to the bottom, as at 14 14. The top of the mold, which becomes one of its sides when in the position for removing the block, is left open. Through this the material is placed in the mold to form the block, and the block is removed when completed. The bottom 11 of the mold is shown with a stone finish, so that one side of the block will be given this impression. The mold is locked together by rods 15 15, one on each side, which arerespectively pivoted at their lower ends to ears 16 16 on the side piece 8 and are locked to ears 17 17 on the opposite side piece 13 by lever-nuts 18 18. Other suitable locking means may of course be substituted for these.

A board 19 is represented upon the side piece 8, on which the block lies when the mold is opened to remove it and on which it may be removed from the mold. Cleats 2O 20 are shown on the under side of the board, that may be necessary if the board is thin or made of several strips. These cleats lie within suitable grooves in the side piece 8.

The mold is secured upon the arms 3 3 and 4 4 of the frame in any suitable manner. In the drawings each of the arms 3 3 is represented as having a pair of inwardly-projecting parallel flanges 21 and 22, which engage, respectively, angular transverse flanges 23 23 on the outside of the side piece 8 of the mold. Clamps 24 24 are respectively secured upon the other arms 4 4 and engage the other side 13 of the mold. (See Fig. 1.)

The mold is easily removed from the frame by first loosening the clamps 24 24 and then withdrawing it from the arms 4 4. When a block is to be formed, the mold is rotated upon its bed into a position at right angles to that shown in Figs. 1 and 3, the cross-bar 6 affording a handle for that purpose. When the block has been made and is to be removed from the mold, the latter is rocked back into the position in which it is shown in Figs. 1 and 3 and is then opened up. When it is opened, the side piece 13 (which will be on top in that position) will be raised and lie back against the arms 3 3, the bottom piece 11 will fall back against the arms 3 3, and the ends 9 9 will also fall away from the block, so that it will lie exposed upon the board 19, which can then be slid out from the mold with the block upon it.

The bed and frame are adapted for molds of different sizes, for they overhang the arms 4 4, and these molds may be substituted one for the other, provided the flanges 23 or other means on the molds for attachment to the frame are placed in corresponding positions on all the molds. Of course if blocks of difierent length, but the same height and thickness, are to be made the same end pieces 9 9 may be used for all the molds, as

they are detachable from the side piece 8,

and so the same sides 8 and 13 may be used for molds of the same length and breadth, but different height, for the mold can readily be taken entirely apart, so as to render these side pieces available also.

The mold-supporting frame is removed from the bed by merely lifting it off, so that the bed, molding-frame, and board can be handled separately.

Another important feature of this apparatusis that the center of gravity of the mold when in position upon the frame lies adjacent to a vertical plane through the segmental bearing on the frame.

What I claim is 1. In a molding apparatus, the combina tion of a mold, an angular mold-supporting frame having an intermediate segmental bearing, and means for removably attaching said mold to said frame.

2. In a molding apparatus, the combination of a bed; having on each side a rack, a

rocking mold-supporting frame consisting of two similar angular parts, rigidly connected together, each having an intermediate gear, adapted to mesh with one of said racks,

whereon said frame is rocked, and a mold on said frame.

3. In a molding apparatus, the combination of a mold-supporting frame; a mold whose ends and bottom are hinged to one of its sides; means upon said mold for locking the parts in their closed positions; and means upon the aforesaid side of said mold whereby it is removably attached to said frame; substantially as shown and described.

4. In a molding apparatus, the combination of a mold supporting frame having flanges; a mold having, upon the outside of one of its sides, flanges that are adapted to engage, respectively, the flanges on said frame, whereby said mold is removably attached to said frame; substantially as shown and described.

5. In a molding apparatus, the combination of a mold, an angular mold-supporting U frame; having an intermediate segmental bearing, and adapted to hold said mold in a position where its center of gravity lies adjacent to a vertical plane through said segmental bearing.
